In complex times of war, some people in order to survive, some people for ambition, resulting in extremely complex human morality; a battle can lead to hundreds of thousands or even tens of thousands of casualties, which will lead to countless families fragmented, and then reorganized families, which also leads to half-siblings can also have a good relationship.
After the early death of Toyotomi Hideyoshi's father, his mother Azhong remarried with the young Toyotomi Hideyoshi and his sister, and later A-Jung gave birth to a son and a daughter with her new husband Takeami, who later became Toyotomi Hidenaga and Asahihihi. Among them, the brotherly relationship between Toyotomi Hideyoshi and Toyotomi Hidenaga is very good, and many people believe that Toyotomi Hideyoshi can ascend to the throne of the world, and his half-brother Toyotomi Hidenaga is indispensable.
Tokugawa Ieyasu was even worse than Toyotomi Hideyoshi, because Toyotomi Hideyoshi's childhood, at least his mother and sister were always with him, and later they got along well with their younger siblings. As for Tokugawa Ieyasu, their family history is too complicated, first of all, Tokugawa Ieyasu's grandfather Matsudaira Kiyonyasu, matsudaira Kiyoyasu was quite strong when he was alive, and directly Gave up his wife Yufu (Huayang-in) to himself.
Mizuno Tadano did not dare to disobey Matsudaira Kiyonyasu's request, so he had to give up his wife to Matsudaira Kiyonyasu, but at that time Yufu already had a daughter with Mizuno Tadao, named Yu Dai (Chuantong-in). However, Matsudaira Kiyonyasu, who had the posture of a tyrant, was assassinated by his courtiers at the age of 25, when his eldest son Matsudaira Hirotada was only 10 years old; after Matsudaira Kiyoyasu's death, Yufu remarried to Hoshino Akiuni, Kannuma Tsunumaki, Kawaguchi Moriyoshi, and so on.
However, Yufu never forgot her son Matsudaira Hirotaru, and when Matsudaira Hirotashi was 16 years old, she arranged for Matsudaira Hirotagi to marry Yu Dai, the daughter of Mizuno Masamune, to show that she had always been with the Matsudaira family, when she was 14 years old. It was only because Mizuno Tadamasa was suffocated, and the good villain was also a city lord, and as a result, his wife and daughter were snatched away by the father and son of the Matsudaira family.
Matsudaira Hirutaka had a good relationship with the half-sister and had a son named Takechiyo, later Tokugawa Ieyasu. However, the two sons were together for less than three years, because of the death of Yu Da's father, and the new brother Mizuno Nobumoto, who was the new governor of the house, allied with Oda Nobuhide, so Imagawa Yoshimoto, who controlled the Mikawa Kingdom behind the scenes, feared that Matsudaira Hirotashi would change his ways, so he forced Matsudaira Hirutaka to divorce Yu Dai.
For various reasons, Matsudaira Hirotada gave in and ended his marriage to Yu Daina for less than three years, and in this way, Theo Tokugawa Ieyasu, who was less than two years old, lost his mother's love; since Yu Dai was only seventeen years old at the time, he soon married again, married to Hisamatsu Toshikatsu, the lord of Akubi Castle in Owari Kingdom, and the two had three boys and four daughters, and the relationship between husband and wife should be OK.
But Tokugawa Ieyasu was not so happy, because his father Matsudaira Yoshinaga's living environment was extremely sinister; when Tokugawa Ieyasu was five years old, Imagawa Yoshimoto asked Matsudaira Hiroshi to send his eldest son to him as a hostage, and Matsudaira Hiroshi had to do what Imagawa Yoshimoto asked to do in order to rely on the Imagawa clan to fight against the Oda clan, but unexpectedly, due to the leak of information, he was "cut off" by Oda Nobuhide's people halfway through.
Originally, Oda Nobunaga thought that he could surrender Matsudaira Hiroshi, but unexpectedly, Matsudaira Hiroshi did not submit to Oda Nobunaga because his eldest son was kidnapped, but remained loyal to Imagawa Yoshimoto as always, which also made Imagawa Yoshimoto feel very pleased. However, Tokugawa Ieyasu's situation was dangerous, and it was at this time that Tokugawa Ieyasu's birth mother Yu Dai learned of the news and quickly asked her husband, Hisamatsu Toshikatsu, to intercede for her son.
Kumatsu Toshikatsu still loves this beautiful wife, so he quickly goes to Oda Nobunaga to intercede, this Kumatsu Toshikatsu is also a talent, but also a city lord, this bit of face still has to be given, and Oda Nobuhide thought that killing Tokugawa Ieyasu would make Matsudaira Hiroshi follow Imagawa Yoshimoto more deadly, so he agreed, but Tokugawa Ieyasu's life was not good.
Fortunately, Yu dai ordered Hisamatsu Toshikatsu's courtiers to give Tokugawa Ieyasu some clothes and food for the four seasons, which allowed Tokugawa Ieyasu to survive and became friends with Oda Nobunaga, the "Owari Fool". However, such a day did not last long, because Matsudaira Hiroshi was also assassinated by his courtiers, and Imagawa Yoshimoto, fearing that Oda Nobuhide would rely on Tokugawa Ieyasu to seize the Mikawa Kingdom, quickly sent troops to attack Anxiang Castle, captured Oda Nobunaga's son Oda Nobunaga, and used this as a condition to offer hostages.
Oda Nobuhide had to agree after considering this, so tokugawa Ieyasu, who was only eight years old, was sent to Suruga Kingdom as a hostage until he was sixteen years old, and did not return to Okazaki Castle in mikawa kingdom until he was sixteen years old, and Imagawa Yoshimoto also placed two female eyeliners around him to observe his every move. In short, tokugawa Ieyasu's puppet life was not changed until after the "Barrel And Narrow Battle", and due to the death of Imagawa Yoshimoto in battle, the Imakawa clan's power was sharply reduced.
Tokugawa Ieyasu thus took the opportunity to break away from the control of the Imagawa clan and quickly unified the Mikawa Kingdom, and also allied with Oda Nobunaga, who defeated Imagawa Yoshimoto, who also trusted this former good friend and handed over the rear to Tokugawa Ieyasu. Later, Tokugawa Ieyasu first mixed with Oda Nobunaga, gained a lot of benefits, and became a daimyō of the million stone level; later mixed with Toyotomi Hideyoshi, becoming a super daimyo of more than two million stones...
After the death of Toyotomi Hideyoshi, he defeated Ishida Sansei in the Battle of Sekigahara, seized the castle, became a shogun of the Seiyi, and formed the shogunate. Since Tokugawa Ieyasu's father basically had no relatives on his side, he was very close to his mother, and perhaps the reason why the Kiyosu Alliance was so easy to reach had a lot to do with his mother Yu Dai, and Tokugawa Ieyasu was also very happy after meeting his father Hisamatsu Toshikatsu and several half-siblings at Oda Nobunaga.
Tokugawa Ieyasu not only gave the matsudaira clan to his three younger brothers, but also to his fiefs; these three younger brothers may have been so ordinary that they are not recorded in history, but they all became more or less daimyōs of the domain, the highest of which was Matsudaira Dingsheng, who received 110,000 stones. Tokugawa Ieyasu was better for his mother, the emperor, the shrine or whatever, and he wanted to see it as if he were visiting his own back garden.
Why is Tokugawa Ieyasu so good to his half-siblings? In fact, it was because Tokugawa Ieyasu's childhood life was so miserable that he had been hostage outside, and his relatives on his father's side were engaged in power struggles all day long, so that Tokugawa Ieyasu could not feel the warmth of family affection at all. Later, when I met my biological mother, I naturally felt very kind, and naturally paid special attention to my half-siblings.
